2D Heat Equation w/ NDSolve

Hello,

I just installed Mathematica 3.0.1, and I'm trying to play with a 2-D
heat equation.  Shouldn't there be a way to fiddle with NDSolve such
that I can get ranges for two spatial dimensions?  It doesn't appear to
be straightforward since the NDSolve inputs like: NDSolve[eqns, u[x,
t], {x, xmin, xmax}, {t, tmin, tmax}], and if I enter a y-variable with
range I get an error complaining about options after the fourth item;
i.e., NDSolve[eqns, u[x,y,t], {x, xmin, xmax}, {y ymin, ymax}, {t,
tmin, tmax}].  

Any help would be much appreciated!

Please e-mail me directly too!
